WASHER IFOR TOP=PROPS.

SPECIFICATION' forming part of Letters Patent No. 313,773, dated March 10,` 1885.

Application filed August 2, 1584.

To @ZZ whom it may concern:

Be it known that I, ERNEsTE Ro'rHLIsBER- GER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Washers for' Carriage-Top Props, of which the following is a specification.

My invention relates to an improved washer for carri age-top props. It is desirable to have the outer faces of both of the washers iinished ornamentally, and it is especially desirable to use patent-leather or other similar enameled goods to iinish the faces ofthe washers. It has been customary hitherto to make these washers of leather bodies and sew them by hand. They are very liable to get out oi' shape, and the finishing of the washers by sewing cracks the enameled goods.

I have invented an improved washer which is stiffer and more durable than the Washers hitherto used, as well as being more ornamental, from the fact that the joining of the parts together does not crack the enamel, and the base of the washer always retains it in perfect condition, so that I obtain at the saine time a more durable as well as a more ornamental iinish for the carriagetop.

Figure l represents a vertical cross-section of my improvement. Fig. Zrepresents a vertical cross-section of a modification ofthe device shown in Fig. l. Fig. 3 is a plan view of the base-plate. Fig. 4 is a plan viewot' the iinished face of the washer; Fig. 5, an elevation of the supporting-plate; Fig. 6, an elevation of the finished washer; Fig. 7, a central cross-section of the modification of' the Washer shown in Fig. l.

A represents the base-plate of the washer. It is made of tin or other light sheet metal.

B represents aconVeX supportingplate rest ing upon the base A, and made of similar material.

C represents the finished washer-surface, made ofpatent-leather or other enameled goods.

D represents a double eup-iiange, the lianges d d being turned down to rest upon the plates A and C and hold them securely together.

(No model.)

All the parts composing the washer are pierced with a square hole to receive the shank of the bolt of the prop-nut.

Fig. 2 is ofthe same construction as Fig. l, except it is provided with a filling, E, of leather or other soft material, to occupymore or less space between the plates A and B. This space between said plates may be entirely iilled with iibrous material, or not, asr desired. When the plates are sprung but slightly apart, the iilling serves to strengthen them in some degree.

Fig. 7 is another modiiicatiou of my improved washer, and ofthe form designed to be used behind' the inner end of the prop. It is made of enameled covering C and baseplates A and B, with the cup-flange D and the parts pierced with the shank-hole a. One thick iirm base-plate may be used in lieu ot' the plates A B. The diii'erence between this and Fig. 1 is that the plates A and B are'not sprung apart to form an oval or convex finished washer, which is the preferred form. These washers can be quickly and cheaply made by dies and iinished without in any Way injuring the enamel of the washer. It may have imitation stitches e formed on the upper ange, d, which are made by being struckup by a die.

I claim- 1. A carriagetop washer composed, substantially, of the plates A E, covering C, pierced with the shank-hole a, and united together by means of cup-flange I), substantially as specitied.

2. A washer for a carriage-top prop, composed, substantially, of the metallic plate A, convex plate B, enameled covering C, each pierced with the shank-hole a, and united together by the annular cup-fiange D,substau tially as specified.

In testimony whereof I have hereunto set my hand.
